To all whom it may concern:

Be it known that we, LAWRENCE H. DICK- QELMANN and JOHN Kuorrnnn, a citizen of the United States and a citizen of the German Republic, respectively, and residents of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Pipe-Clips and Methods of Forming Same; and we do hereby declare that the following is a full,

. clear, and exact description thereof.

- improvements in increased strength of increased which they Our invention relates'to new and useful clips for securing pipes or other members to a support, more particularly of that type including a body portion adapted to embrace the member to be secured, and having prongs bent therefrom to e driven into the support, our invention residing-in the method of forming the clip, as well as in certain advantageous structural features'thereof.

It is primarily the object of our invention to provide aclip of this character which is stamped from a single blank of sheet metal, and wherein portions are so arranged as to effect a bracing action the clip.

More particularly, it is our object to provide a clip of this character having secur ing prongs bent therefrom and formed of a double thickness of metal to procure an gripping action inthe support in are driven, to provide increased strength, and further effecting an arrangement wherein the addedthickness of metal forms a brace at the juncture of the prong with the body of the clip.

v A further object resides in the provision of a method of forming the clip wherein notches for the sides of the double thickness prongs are formed incidental to stampwhich ing out the body blank of the clip.

With the above and other objects and advantages in view, which will be apparent as the description proceeds,- our invent-ion resides in the novel features of construction, combination and arrangement of parts as hereinafter more particularly described and,

defined by the appended claims.

In the accompanying drawings: Figure 1 is a side elevational view of a clip embodying our inventio 1 Fig. 2 is an end elevational view of the 0 1p.

Fig. 3 is a plan view of a blank from our improved clip is formed, and

procuring an- Referring now more particularly to the accompanying drawings, our improved clip in its finishedshape comprises a bowed and longitudinal ribbed intermediate body section 5, from the ends of which extend outwardly bent support abutting end sections 6 having prongs 7 projecting from their outer portions for engagement in the support to which it is" desired to secure the cli said prongs being each thickness of metal integrally connected along one side edge of the prong.

The first step in our method of forming the clip is to stamp the body blank thereof as shown in Fig. In this body blank, it'is noted that the outer portions of the end sections 6 are reduced whereby their juncture with the prong blank portions is of considerably lesser width than the general width of the end and intermediate sections and the inner and outer side portion 'a and b respectively of the prong blanks are adapted to be bent on the longitudinal line 0, the inner end of the outer prong side portion affording the connection with the end sections, while the inner end of the inner side portion a is free from such connection, being however substantially in alinement with the bending line of the connection. The free edges of the. prong side portions are. provided with corresponding series of notches d. The blank i then placed .m the press to afford the bowed and rib The final step formed of a doub e b 3 from a sheet of metal.

'orming the double thickness of the prongs,

7 thus disposing the inner end of the prong side portion a in abutting engagement with the under faces of the end sections 6 to afford braces for the prong sections prevent-' ing inward bending movement thereof past the same time, the notches d of the prong sides are brought into registryand thus the complete clip is afi'orded in a manner avoiding the necessity of any cutting operations subsequent to the initial stamping out step.

' In some instances, it may be desired to afford additional securing means for the clip and to this end, the end sections are I provided with apertures 8 for the reception ioo fight-angular relation to'the end sections.-'

of screws, nails or the like. It may. in still other conditions, such as in attaching the clip to a plastered surface, not be desirable be appreciated that to meet diflering condi-' tions, various changes and modification of structure and operative steps may be employed without departing in any manner from the spirit of our invention.

What is claimed is 1. A clip of the class described including a'bowed body section, end sections extending from the ends of said body section and disposed in a common plane, and prongs extending from the outer portions of the end sections, the cross sectional areas of the prongs at their points of juncture with the end sections being les than other cross sectional areas of the prongs, the metal of said gron 5 being bent longitudinally to aiford oub e thickness for the prongs. 2. A clip formed of sheet metal and com- 1,32s.2es

prising a bowed body section, end sections extending from the ends of the body section, and prongs bent from theends of the end sections the metal of said prongs being bent longitudinally to form inner and outer side portions, the inner ends of the inner prong side portions abutting the end sections to brace the prongs.

3. The method of forming a clip which consists in stamping out abody blank having prong portions extending from the ends thereof and in simultaneously cutting notches in the sides of the prong portions adapted to register and in then bending said prong portions together longitudinally whereby to form double thickness prongs and to dispose the notches of the side portions of each prong in registry, and bendin the 'body blank to form the clip and ben ing the prong portions to project at right angles from the adjacent portions of the In testimony that we claim the foregoing we have hereunto set our hands at Mil--- waukee, in the county of Milwaukee and State of Wisconsin.
